Under what circumstances should I do four wheel alignment?
1. The driving performance of the vehicle is affected (the driver's feeling is the most direct deviation, and the direction is not automatic.)
2. Damage to the chassis and suspension caused by the accident.
3, tires wear abnormalities (but also consider whether the abnormal tire pressure caused by abnormal wear, in general, the tire pressure is too high will increase the wear of the center of the tread, and the tire pressure will increase the tread Wear on both sides; if eccentric wear occurs on one side, there may be a deviation in the camber angle.)
4. The axles and suspension parts have been removed.
